[R-390] re: Call for measurements - 100dB carrier reading

[Jim M.]

I have used the Vishay/Spectrol 10-turn pot available from Mouser.  This is 
the one I recall using (it's been a few years):

Data sheet:
http://www.mouser.com/catalog/628/548.PDF

Mouser part number for pot:  59453411101
http://www.mouser.com/search/Refine.aspx?Ne=1447464+254016&Ntt=*59453411101*&Msb=0&Mkw=59453411101&N=1323038

The 10 turn pot will give much better zero adjustment and won't drift like a
single turn pot.  It's just small enough to fit under the bracket on the IF
module.

The wire wound pot described in the cost reduction report is probably a 
single turn, not  a precision 10 turn.
